Description
本発明は、セルロース系繊維を含有する布帛に関する。より詳細には、吸湿性がありながら多量の発汗時のべたつき低減効果に優れた布帛およびそれからなるスポーツウエアに関する。 The present invention relates to a fabric containing cellulosic fibers. More specifically, the present invention relates to a fabric excellent in the effect of reducing stickiness when sweating a large amount while being hygroscopic, and sportswear comprising the same.
従来、スポーツウエアには強度が強く、汗をかいてもべたつきが少ないことからポリエステル繊維が広く使用されている。しかしながらポリエステル繊維は疎水性繊維であり、吸湿性が乏しいため、着用時の不感蒸泄や、少量でも汗をかいた場合にはポリエステル繊維100%のスポーツウエアでは蒸れが生じ、着用感は不快である。
このため、綿やレーヨンなどの吸湿性に優れるセルロース繊維とポリエステル繊維などの疎水性繊維とを複合、あるいは交編、交織し、吸湿性を付与した布帛から構成されるスポーツウエアも広く使用されている。しかしながら綿やレーヨン繊維等のセルロース繊維は繊維自身の水との親和力が大きいため汗などの液体の水分を保持しやすく、一旦保持された水は拡散させにくいため、特にスポーツ時などで多量の汗をかいたときにべたつきが増大し、不快となる。また、綿やレーヨン繊維等のセルロース繊維は乾きも遅いため、汗が冷えるとさらに不快となる場合が多く、ポリエステル等を混用してもべたつきの低減効果は十分ではなかった。また、綿やレーヨン繊維は繊維比重が大きく嵩高性と軽量感に欠け、さらに、洗濯を繰り返すと水による膨潤、乾燥が繰り返されるため糸が膠着し、風合いが硬くなり、着用などで布帛が伸張された後の伸長回復率の低下が起こりやすいという問題点があった。
Conventionally, polyester fiber has been widely used for sportswear because of its high strength and low stickiness even when sweated. However, polyester fiber is a hydrophobic fiber and has poor hygroscopicity. Therefore, if you sweat even with a small amount of sweat, or if you sweat even a small amount, it will cause stuffiness in sportswear with 100% polyester fiber, and the feeling of wearing will be uncomfortable. is there.
For this reason, sportswear is also widely used, which is composed of a fabric that has been combined with, or knitted or woven with, cellulose fibers that are highly hygroscopic, such as cotton and rayon, and hydrophobic fibers, such as polyester fibers. Yes. However, since cellulose fibers such as cotton and rayon fibers have a high affinity with the water of the fibers themselves, it is easy to retain liquid moisture such as sweat, and the water once retained is difficult to diffuse. When touching, stickiness increases and becomes uncomfortable. In addition, since cellulose fibers such as cotton and rayon fibers dry slowly, they often become more uncomfortable when the sweat cools, and even if polyester or the like is mixed, the effect of reducing stickiness is not sufficient. In addition, cotton and rayon fibers have large fiber specific gravity and lack bulkiness and lightness. Furthermore, when washing is repeated, swelling and drying with water are repeated, causing the yarn to stick together, the texture becomes hard, and the fabric stretches when worn. However, there is a problem that the elongation recovery rate is likely to decrease after being applied.
一方、高捲縮セルロースフィラメントを用いた編織物が記載されている(例えば、特許文献1参照)が、スポーツウエアに最適な布帛、すなわち、多量の発汗に対応するためには本発明に示した限定された混用方法が必要であり、それらについて何ら記載されていない。
本発明は、上述した従来技術の問題点を解決し、吸湿性がありながら発汗時のべたつき低減効果に優れ、洗濯による風合い変化が小さい、スポーツウエアに最適な布帛を提供することにある。 An object of the present invention is to solve the above-described problems of the prior art, and to provide a fabric that is optimal for sportswear, which is hygroscopic and has an excellent effect of reducing stickiness during sweating, and has a small change in texture due to washing.
本発明者は前記課題を解決するため、以下の構成要件を見出し、本発明を完成した。
即ち、本発明は下記の通りである。
(1)沸水処理後の伸縮伸長率(SB)が4%以上50%以下であるセルロース系繊維を構成糸の全体重量の15〜60%、疎水性繊維フィラメントを構成糸の全体重量の40〜85%含有されていることを特徴とする布帛。
(2)30℃90%での吸湿率が3.5%以上であり、べたつき指数が1.5以下である上記1に記載の布帛。
(3)疎水性繊維フィラメントがポリエステル異型断面繊維である上記1または2に記載の布帛。
(4)洗濯30回後の曲げ応力の変化率が150%以下である上記1〜3のいずれかに記載の布帛。
(5)上記1〜4のいずれかに記載の布帛を用いてなるスポーツウエア。
In order to solve the above-mentioned problems, the present inventor has found the following constituent elements and completed the present invention.
That is, the present invention is as follows.
(1) Cellulose fibers having a stretch elongation (SB) of 4% to 50% after boiling water treatment are 15 to 60% of the total weight of the constituent yarns, and hydrophobic fiber filaments are 40 to 40% of the total weight of the constituent yarns. A fabric characterized by containing 85%.

(3) The fabric according to 1 or 2 above, wherein the hydrophobic fiber filament is a polyester atypical cross-section fiber.
(4) The fabric according to any one of the above 1 to 3, wherein the rate of change in bending stress after washing 30 times is 150% or less.
(5) Sportswear using the fabric according to any one of 1 to 4 above.
本発明の布帛は、吸湿性がありながら多量の発汗時にもべたつき低減効果に優れ、スポーツウエアに最適な布帛である。さらに肌との皮膚摩擦低減効果に優れ、洗濯を繰り返しても風合いが硬くならない布帛である。 The fabric of the present invention is a fabric that is excellent in stickiness reduction effect even when sweating a large amount while being hygroscopic, and is optimal for sportswear. Furthermore, it is a fabric that is excellent in the effect of reducing skin friction with the skin and that does not harden the texture even after repeated washing.
本発明について以下に具体的に説明する。
本発明は、沸水処理後の伸縮伸長率(SB)が4%以上好ましくは7%以上、特に好ましくは10%以上、50%以下のセルロース系繊維を用いることに最大の特徴があり、SBが4%以上であるとき疎水性繊維フィラメントと所定の割合で混用して編織物となした時に十分なべたつき低減効果が得られる。一般のアウターやインナーでは汗ばむ程度の発汗すなわち80g〜120g/m2の汗に対する汗処理、すなわち吸水性やべたつき防止性が必要とされるが、スポーツウエアはアウターやインナーとは異なり、かなり多量の発汗すなわち200〜250g/m2の汗に対する汗処理が必要とされる。ウエア用生地のべたつき低減効果は繊維の吸水拡散性が大きく繊維と肌との接触面(表面層)に水分が少ないほど高く、すなわち、繊維が一方向に並んでいる場合に拡散が促進され、かつ、嵩高で点接触となる場合に高いべたつき低減効果が得られる。本発明のセルロース系繊維は伸縮伸長率が非常に大きく、嵩高であるため、生地と肌との接触が点接触となり非常に良好な汗処理性を有する。
The present invention will be specifically described below.
The present invention has the greatest feature in using a cellulosic fiber having a stretch elongation (SB) after boiling water treatment of 4% or more, preferably 7% or more, particularly preferably 10% or more and 50% or less. When it is 4% or more, sufficient stickiness reduction effect can be obtained when it is mixed with a hydrophobic fiber filament at a predetermined ratio to form a knitted fabric. In general outer and inner sweating, sweating to a degree that sweats, that is, sweat treatment for sweat of 80 to 120 g / m 2 , that is, water absorption and anti-sticking properties are required. A sweat treatment for sweating, ie 200-250 g / m 2 of sweat, is required. The stickiness reduction effect of the fabric for wear is so high that the water-absorbing and diffusing property of the fiber is large and the moisture is small on the contact surface (surface layer) between the fiber and the skin, that is, the diffusion is promoted when the fibers are aligned in one direction, In addition, a high stickiness reduction effect can be obtained in the case of bulky point contact. Since the cellulosic fiber of the present invention has a very large expansion / contraction rate and is bulky, the contact between the fabric and the skin becomes a point contact and has a very good sweat treatment property.
尚、SBが大きすぎると、嵩高性は大きくべたつき低減効果は高いものの、凹凸感のある編織物となり外観が損なわれ、さらに肌への摩擦係数も大きくなり好ましくない。なお、伸縮伸長率はJIS L1090伸縮性試験法(A法)に準じて、またべたつき性は実施例に記載した方法でべたつき指数を測定した。べたつき指数が1.5以下であればべたつき防止性に優れることは、以下の実験により確かめられている。すなわち、この方法で各種のべたつき指数をもつ布帛でTシャツを作成し、200g/m2の水を背部に与え、べたつき感を官能検査したところ、べたつき指数と官能によるべたつき感には高い相関が有り、べたつき指数が1.5以下ではべたつきを感じにくいことがわかった。SBが4%以上であると疎水性繊維フィラメントと所定の割合で混用して編織物となした時に十分なべたつき低減効果が得られる。本発明のSBが4%以上であるセルロース系繊維と疎水性繊維フィラメントと所定の割合で混用して編織物となした時にはべたつき指数が1.5以下となり、十分なべたつき低減効果が得られる。 If SB is too large, the bulkiness is large and the stickiness reduction effect is high, but the knitted fabric has a feeling of unevenness, the appearance is impaired, and the coefficient of friction to the skin is increased, which is not preferable. The stretch elongation was measured in accordance with JIS L1090 stretch test method (Method A), and the stickiness was measured by the method described in the examples. It has been confirmed by the following experiment that if the stickiness index is 1.5 or less, the stickiness prevention property is excellent. That is, when T-shirts were made with fabrics having various stickiness indexes by this method, 200 g / m 2 of water was given to the back, and the stickiness was subjected to a sensory test, there was a high correlation between the stickiness index and the stickiness due to sensuality. Yes, it was found that the stickiness index was less than 1.5 and it was difficult to feel stickiness. When the SB is 4% or more, a sufficient stickiness reducing effect can be obtained when the woven fabric is obtained by mixing with a hydrophobic fiber filament at a predetermined ratio. When the SB of the present invention is mixed with a cellulose fiber having a SB of 4% or more and a hydrophobic fiber filament to form a knitted fabric, the stickiness index becomes 1.5 or less, and a sufficient stickiness reduction effect is obtained.
本発明においてさらに好ましい要件としては、沸水処理前後の伸縮伸長率の比(SB/S0)が0.5以上特に好ましくは0.7以上、10以下であると、疎水性繊維フィラメントと混用して編織物となした時に極めて大きな嵩高性が得られ、べたつき低減効果に優れる。SB/S0が0.5以上では、精練や染色に基づく熱水処理で嵩高性が損なわれることがなく、10以下では、嵩高性は大きくべたつき低減効果を保持しつつ、凹凸感の少ない編織物となり外観が良好で、肌への摩擦係数も小さくなり好まい。SB/S0とは、沸水処理して乾燥した後の伸縮伸長率(SB)と、沸水処理前の伸縮伸長率(S0)との比である。 In the present invention, the more preferable requirement is that the ratio of the stretch elongation before and after the boiling water treatment (SB / SO) is 0.5 or more, particularly preferably 0.7 or more and 10 or less, and mixed with the hydrophobic fiber filament. When it becomes a knitted fabric, extremely high bulkiness is obtained, and the stickiness reduction effect is excellent. When SB / S0 is 0.5 or more, the bulkiness is not impaired by hot water treatment based on scouring or dyeing, and when it is 10 or less, the bulkiness greatly maintains the stickiness reduction effect and has a less uneven feeling. Appearance is good and the coefficient of friction on the skin is small. SB / S0 is the ratio of the stretch / elongation rate (SB) after the boiling water treatment and drying to the stretch / elongation rate (S0) before the boiling water treatment.
さらに本発明においては、X線回析による算出法(後記する)にて、セルロースIV型結晶成分が20%以上,好ましくは20〜60%混在するのが好ましい。この範囲であると、セルロースIV型の特徴である湿潤処理による形態保持性が充分に発揮される。
このような沸水処理後の伸縮伸長率(SB)が4%以上のセルロース系繊維としては、綿、麻等の天然繊維、ビスコースレーヨン、キュプラアンモニウムレーヨン、ポリノジックレーヨン、精製セルロース繊維(テンセル、リヨセル)などの人造セルロース繊維があり、これらの一種又は二種以上を混用したものをいう。
繊維の形態は、長繊維でも短繊維でもよく、長さ方向に均一なものや太細のあるものでもよく、断面においても丸型、三角、L型、T型、Y型、W型、八葉型、偏平(扁平度1.3〜4程度のもので、W型、I型、ブ−メラン型、波型、串団子型、まゆ型、直方体型等がある)、ドッグボーン型等の多角形型、多葉型、中空型や不定形なものでもよい。
Furthermore, in the present invention, it is preferable that the cellulose IV type crystal component is mixed in an amount of 20% or more, preferably 20 to 60%, by a calculation method by X-ray diffraction (described later). Within this range, the form retention due to the wet treatment, which is characteristic of cellulose type IV, is sufficiently exhibited.
Cellulose fibers having a stretch elongation (SB) of 4% or more after boiling water treatment include natural fibers such as cotton and hemp, viscose rayon, cupra ammonium rayon, polynosic rayon, purified cellulose fibers (Tencel, Lyocell). ) And the like, and a mixture of one or more of these.

一般に綿やレーヨンなどのセルロース系繊維は洗濯後通常の吊り干し乾燥を繰り返すと糸が膠着し、風合いが硬くなり、伸長回復率の低下や繊維の脱落による薄地化が起こりやすいという問題がある。本発明の沸水処理後の伸縮伸長率(SB)が4%以上であるセルロース系繊維の場合には糸の嵩高性から膠着が起こりにくく、洗濯と乾燥を繰り返した場合の風合硬化と薄地化を軽減するとともに、伸長回復率の低下をも防ぐことができる。繰り返し洗濯による風合い硬化にはKES法による曲げ応力変化が指標となり、本発明のセルロース系繊維を構成糸の全体重量の15〜60%に用いた布帛の場合には洗濯30回後の曲げ応力の変化率が150%以下となり、風合い変化が小さく好ましい。セルロース系繊維を構成糸の全体重量の15〜40%に用いた布帛の場合には洗濯30回後の曲げ応力の変化率が130%以下となり、特に好ましい。 In general, cellulosic fibers such as cotton and rayon have the problem that if they are repeatedly hung and dried after washing, the yarns stick together, the texture becomes hard, and the elongation recovery rate decreases and thinning of the fibers is likely to occur. In the case of cellulosic fibers having a stretch elongation ratio (SB) of 4% or more after boiling water treatment of the present invention, stickiness hardly occurs due to the bulkiness of the yarn, and texture hardening and thinning when repeated washing and drying are performed. As well as a reduction in the elongation recovery rate. Changes in bending stress by the KES method are used as an index for texture hardening by repeated washing, and in the case of a fabric using 15 to 60% of the total weight of the constituent yarn of the cellulose fiber of the present invention, the bending stress after 30 washings The rate of change is 150% or less, and the texture change is small and preferable.

The present invention is a fabric containing 15 to 60% of the total weight of the constituent yarn and the hydrophobic fiber filaments of 40 to 85% of the total weight of the constituent yarn.

上述のセルロース系繊維と疎水性繊維フィラメントの混用の方法は交編、交織による方法が好ましく行われるが、交撚、カバリング(シングル、ダブル)、複合仮撚(同時仮撚、先撚仮撚(先撚同方向仮撚や先撚異方向仮撚)、位相差仮撚、仮撚加工後に後混繊)、2フィード(同時フィードやフィード差をつけた)空気噴射加工等の手段で混用してもよい。
布帛の目付けは80g〜300g/m2である事が好ましい。一般に目付けが大きいと発汗量が同じであれば繊維表面に配される水分は少なくなるため、べたつきは低減される方向にあるが、本発明の布帛では目付けが120g以下の布帛であっても非常に高いべたつき低減効果を有する。
In the fabric of the present invention, when the hydrophobic fiber filament is 40% or more of the total weight of the fabric constituting yarn, the fabric has sufficient strength and can be used for sportswear. When the hydrophobic fiber filament is 85% or less of the total weight of the fabric constituting yarn, the hygroscopicity is sufficient, and it is preferable that stuffiness does not occur during sweating.

The fabric weight is preferably 80 g to 300 g / m 2 . In general, when the basis weight is large, if the sweating amount is the same, the amount of moisture distributed on the fiber surface is reduced, so that the stickiness tends to be reduced. However, the fabric of the present invention is very easy even if the basis weight is 120 g or less. High stickiness reduction effect.
